Title: Color reagent for vanadium compound
Inventor: HAYASHI YUKIO
IPC: G01N21/91
Filed: 1979-05-09
Abstract: PURPOSE: To provide a color reagent characterized by an inorg. acid contained and easily discriminating a V compound from boiler refractories when the compound penetrated into the refractories is removed.  
     CONSTITUTION: This color reagent contains about 0.3 N or more of an inorg. acid such as hydrochloric acid, sulfuric acid or nitric acid. When a V compound penetrated into boiler bottom refractories is removed at the time of stopping the boiler, this reagnet is sprayed upon the refractories with a sprayer to turn the V compound surface reddish brown. Thus, the compound whose color tone is about equal to that of the refractories is removed and recovered effectively and easily, and at the same time, corrosion of a skin casing and an evaporation pipe attached to the bottom of a boiler fire furnace can be prevented.

Title: Position control method for electrostatic floating object
Inventor: OGIWARA MASAAKI
IPC: G05D3/12
Filed: 1992-02-10
Abstract: PURPOSE:To return an electrostatically floating object electrically to an original position upon positional shift thereof. CONSTITUTION:An AC voltage is applied on two-dimensional quadruple electrodes 1a, 1b, 1c, 1d in order to confine an object 2 within the central part 7 between electrode. A DC voltage is subsequently applied between DC electrodes 4, 5 disposed, respectively, above and below the central part 7 thus vertically confining the object 2. The stationarily floating object 2 at one point in the space subsequently begins to move through function of disturbance. Position of the object 2 is then detected and only when the position is shifted significantly, a DC voltage is applied onto the two-dimensional quadruple electrodes 1a, 1b, 1c, 1d thus resetting the object 2 through repellency.

Title: New addition record-type optical disk
Inventor: HAYASHI YOSHIO
IPC: G11B7/243
Filed: 1990-03-09
Abstract: PURPOSE:To provide a disk in which additional data can be recorded freely and which withstands any severe use environments and can be used for data recording and reproduction regardless of time and place by providing a recording material containing a recording layer in which metal silver fine particles are dispersed in a hydrophobic binder so that the reflection factor of a bit formation part is reduced. CONSTITUTION:A recording material used for writing in a disk, information converted in the form of a digital signal using a semiconductor laser consists of a recording layer in which metal silver fine particles having about 70% or higher of reflective factor are dispersed in a hydrophobic binder. Thus the reflective factor of a bit formation part is reduced. Under this constitutions, a silver fine particle-dispersed layer adjoining the surface of a disk substrate becomes the same as a conventional compact disk of optically basic constitution. In addition, the hydrophobic binder of the silver fine particle layer acts as an important factor for controlling the physical properties of the layer. Further, this important silver fine particle layer is formed between the hydrophobic binder and the disk substrate layer.

Title: Air conditioner
Inventor: FUKUSHIMA AKIO
IPC: F24F11/02
Filed: 1993-03-17
Abstract: PURPOSE:To expand the operation range in which a cooling operation can be performed continuously by opening a by-pass solenoid valve when a sensed temperature reaches a first set temperature during a cooling operation and stopping a compressor emergently when the sensed temperature reaches a second set temperature. CONSTITUTION:During a cooling operation, when an outlet pipe temperature T of an outdoor heat exchanger 3 exceeds a first set temperature (T1: 60 deg.), a by-pass solenoid valve 10 is opened, whereby the load of a compressor 1 is reduced. When, under conditions that the valve 10 is open, the outlet pipe temperature T of the exchanger 3 exceeds a second set temperature (T2: 67 deg.C), the compressor 1 is stopped emergently to protect it. And when, under conditions that the valve 10 is opened, the outlet pipe temperature T of the exchanger 3 falls below a third set temperature, the valve 10 is closed to restore its original condition. By opening the valve 10, the range of the operation is expanded and hence even if the suction temperature of the exchanger 3 rises, the cooling operation can be continued.
